So I TOFTT at Saa and it was... just OK.
One woman band run by 40-something Mo, a pleasant looking Thai woman who was obviously hot hot hot 20 years ago but has now run a bit to seed.
Positives* reasonably attractive MILF, 5ft nothing with probably a C-cup rack, not that I got to see it
* friendly and chatty
* v.good to excellent massage technique
* massage therefore decent value at £40 the hour
* lots of free parking in surrounding side streets
Negatives* The price of extras
* Hard-nosed businesswoman
To explain - I enquired about extras and she was very up front: clothed HE £30, B2B £80

and on further discussion it turns out B2B means topless only

Absolutely nothing else on offer and not a penny off the published prices. Also she said she has help during the week and they are strictly legit only.
Negotiations were in a pleasant tone but brisk and no-nonsense and in the excitement (!) my bratwurst became a chipolata so I declined even HE.
Conclusions* Definitely worth it for legit message if you're nearby
* Not really worth a visit if you want anything extra
